Is there an easy way to test if my wallet is working?

It is linked to mining.bitcoin.cz and I can see the work my miner is doing, but I'm not sure if it can move what it earns into the wallet.

I just tried now, it still only displays balance to 2 decimal places.

Ok, so I'm very new to Bitcoin, or at least, new to mining it. I'm also new to this forum as it happens, so hi there!

I've been mining Bitcoin and I'm using Multibit as a wallet, but the balance says 0.00. This amount is totally expected since as I've only been mining for a very short time, but my concern is that bitcoins are usually shown up to something like 8 decimal places, and it can take some time to get even 0.01 bitcoin. I see that on Bitcoin Core, you get a balance that looks something like this; 0.00034253. So basically, any profit I make below 0.01, I can't actually see, which means I could be staring at 0.00 balance for some time. What am I doing wrong?

Yes I'm a noob, I'm here to educate myself.

Thanks in advance for any help you guys can offer me!

EDIT: Sorry, it seems there is a specific location for this type of query (i.e. Alternative Clients boards > Multibit), if it can be moved, that would be awesome!
